I'm curious about the companies where the author has worked, because they must be using a lot of open source libraries internally. If the author's GitHub profile is completely bare, then it means they've never forked a library to fix a bug, or added a new feature and submitted a pull request. I don't care if you don't do that in your spare time. I don't know what languages or frameworks the author uses, but I probably won't hire a Rails or React developer if they'v never contributed to any open source projects. If they've never come across a single gem or npm package that needs a bug fix or a new feature, then they probably don't have enough experience.
